WASHER 63000434 - Caterpillar

Do not install the timing calibration probe over the timing pin hole at the flywheel or damage will result.
Tighten the nut on the 6V-3093 Transducer Adapter .
Connect the 7X-1695 cable between the Magnetic Transducer and the timing calibration connector P26.
Turn the keyswitch to the START position. The engine should be running.
Allow the engine to exit cold mode operation.Expected Result:Only CID-FMI 261-13 is active.Results:
OK - CID-FMI 261-13 is the only active code at this time. Proceed to Test Step 2.
Not OK - CID-FMI 261-13 is not the only active code at this time.Repair: Repair any active diagnostic codes. Other active diagnostic codes cannot be active during calibration. Stop.Test Step 2. CalibrationNote: The speed/timing sensor is calibrated through a two-step process. A new timing reference is calculated first. The reference is based on the signals from the transducer and from the engine speed/timing sensor. Next, the new timing reference is programmed into the permanent memory of the engine ECM.
Select "Service" from the main menu on Cat ET. Select "Calibrations" from the drop-down menu. Select "Timing Calibration".
Press the "Continue" button on Cat ET.Note: Engine speed will be set to 800 rpm by the ECM during the calibration.Cat ET indicates "Please wait...Calculating the new Timing Reference". After a few moments, Cat ET will display "The ECM has calculated the Timing Reference" and "Choose the Continue button to program the Timing Reference".Note: If Cat ET indicates "CALIBRATION UNSUCCESSFUL", the electronic injection timing has not been set.Expected Result:Cat ET indicates "CALIBRATION SUCCESSFUL".Results:
OK - The timing calibration was successful.Repair: Disconnect the timing calibration probe before you exit the "Timing Calibration" screen on Cat ET. Reset the system and check for any diagnostic codes. Stop.
Not OK - The timing did not calibrate.Repair: Excessive backlash in the engine gear train will cause inconsistent timing. Refer to Systems Operation for identifying and repairing a gear train problem. Stop.
